| 摘 要： | 对海南乐东的次生林、大叶相思(Acacia auriculiformis)、木麻黄(Casuarina equisetifolia)、桉树(Eucalyptus robusta)、椰树(Cocosnucifera)等5种典型森林土壤有机碳含量、密度及储量进行了比较分析。结果表明,5种森林0~100 cm土壤有机碳平均含量介于1.55~8.52 g/kg,以次生林最高,大叶相思和木麻黄最低;5种森林0~100 cm土壤有机碳密度介于1.51~9.49 kg/m~2,以次生林最高,木麻黄最低;5种森林0~100 cm土壤有机碳储量分别为次生林94.86 mg/hm~2、椰树73.72 mg/hm~2、桉树44.93 mg/hm~2、大叶相思30.80 mg/hm~2、木麻黄15.10 mg/hm~2,4种人工林土壤碳储量要低于天然次生林。

| Abstract: | Soil samples were collected from the soil 0~100 cm deep from 5 different forest plantations (Secondary forest, Acacia auriculiformis, Casuarina equisetifolia, Eucalyptus robusta, Cocos nucifera) in Ledong county of Hainan province to determine the content, density and storage of organic carbon in the soils under the forest plantations. The results showed that the organic carbon content in the soil 0~100 cm deep ranged from 1.55 to 8.52 g/kg from the soil samples of the 5 plantations, the highest in the secondary forest and the lowest in the plantations of both A. auriculiformis and C. equisetifolia. The soil organic carbon density ranged from 1.51 to 9.49 kg/m2, the highest in the secondary forest and the lowest in C. equisetifolia. The soil organic carbon storage was 94.86 mg/ha in the secondary forest, 73.72 mg/ha in A . auriculiformis, 44.93 m g/ha in C. equisetifolia, 30.80 mg/ha in E. robusta and 15.10 m g/ha in Cocos nucifera. The secondary forest had the highest organic carbon storage in the soil. |
